Or if you have a Netapp with a decent support contract: A disk fails while you're asleep[1]. The filer notifies Netapp over a dedicated POTS line. Netapp overnights a new disk to you. You find out the next morning that the disk failed, via a call from the loading dock about a package for you. You pop in the new drive, activate one of your other hot spares, and configure the new drive as a new hot spare, all in less time than it took you to walk down to the loading dock and back.

[1] You don't have single disk failure alarms wake you up in the middle of the night because you configured your array to run with two failed disks.

Yeah, going to Maker Faire makes you think the only thing anyone ever prints are tchotchkes from Thingverse.

One application is to reproduce plastic parts that are otherwise unobtainable. Example:

I have a turntable microwave oven that was built almost 25 years ago. There's a piece of plastic about the size of a pair of dice that 's effectively the turntable spindle. Somebody turned the thing by hand and snapped that piece of plastic. I have a part number for it but nobody sells it any more. A chunk of the part is missing, but its shape isn't too complicated, and enough of it is still there, that I can make an STL file for it.

That in itself is not enough to make buying a 3D printer worthwhile, but I can contract that out to someone on 3D Hubs to print it for me out of ABS.

Of course usable 8K is a long way off. Even movie theater projectors are still 4K. That's why they're showing it at CES, not in the Best Buy.Black Friday doorbuster circular. CES is all about mine's-bigger-than-yours.

Personally, I'd rather see the frame rate go up rather than resolution. The standard for 4K movie theater projection is 250Mbps, which is only enough for 24fps. The standard also specifies compression limits so that picture quality won't suffer too much. At 1Gbps, you could compress it even less, and still project at 60fps. If you ever saw a Showscan movie back in the 80s, you know the difference in realism the higher frame rate makes. (BTW, the audio is up to 16 channels of uncompressed .wav at 24-bit, 48Khz or 96Khz sampling. I guess they decided that lossless compression for audio wouldn't save enough bandwidth to matter, compared with the video stream.)

As someone said - what percentage of crime is committed by blacks?
Further, even if you don't believe that look at this map...

Then do man ethnic overlay. Except for midtown, it strongly correlates with race, and if you stop and frisk in high crime neighborhoods, on even a proportional basis to the neighborhood, you will end up with a minority bias/ MOST crime in NYC is in minority neighborhoods...

Don't be irreplaceable, if you can't be replaced, you can't be promoted.
